Eaton Motor Protection Circuit Breaker, 25g Mechanical Shock Resistance, Phase Failure Sensitive - PKE Series - 121722 PKE32
Run your industrial machinery without risk of damage from electrical hazards with this motor protection circuit breaker from Eaton. It keeps a close eye on your network and instantly cuts power to downstream equipment if there's a short circuit or overload. The unit's 3-pole construction gives you multi-circuit control in three-phase setups and reduces the wiring needs of the system. Thanks to a simple rotary knob, it's easy to operate. The component comes with finger-proof screw terminals, reducing the risk of electric shock from contact with live parts. You’ll find MPCBs like this commonly used in the transportation industry.

What's the difference between a circuit breaker and a fuse?
A fuse is a sacrificial item that's designed for single use and needs to be changed after it blows. This kind of circuit breaker is designed for multiple uses and can be reset time and again after it trips.
